SCI-IADE, OF HOLYOKE, MASSACHUSETTS, ASSIGNOR TO NATIONAL BLANK BOOK COMPANY, OF HGLYOKE, MASSACHUSETTS, A CORPORATION OF MASSACHU- SETTS BOOK COVER Application filed October 28, 1930. Serial No. 491,652.

This invention relates to book covers, but more particularly has reference to the attachment of a non-abrasive material to the edges of such covers, so that the latter will be noiseless in use and will not slip on or mar the surface of a desk or table.

Referring to the accompanying drawings which form a part of this description Figure 1 is an outer face view of a book cover equipped with the invention Figure 2 is a cross section at the line 22 of Figure 1- Figure 3 is a section at the line 33 of Figure 1, and

Figure 4 is a section at the line 4-4: of Fig ure 1.

Similar numerals of reference denote like parts in the several figures of the drawings.

The book covers, to which the present invention is applied, are back and front covers that are hinged at their edges to the sheet holding structure, and are made from a material such as wood pulp or cellulose that has a distinctly hard surface.

The invention may be applied to both the back and front covers, as may be desired, but there is shown in the drawings, and will be hereinafter described, a bottom cover, since the latter comes in contact with a desk or table when in use.

Referring to the drawings, 1, 2, are respectively the outer and inner faces of the cover, and 3 is the protective edging which is applied to the cover, this edging, in the present instance, consisting of a channeled rubber strip which has a comparatively thick body portion a and resilient lips 5 which are the sides of the channel part of the edging.

In applying the invention the edging strip 3 is positioned along the bottom and side edges of the cover and the upper corners, and the strip is then stretched so as to place the entire edging under a tension, and clips 6 which embrace the end portions of the edging are then secured to the top portion of the cover by means of rivets 7 whereby the extremities of the edging will be firmly held under tension.

Hinge eyes 8 are preferably formed at the outer ends of these clips so that similar eyes on the sheet holding structure may be alined therewith and an ordinary pintle passed therethrough.

It will be observed that the ends of the edging are near the upper corners of the cover, and since the edging is positioned around these corners at a tension, the corners themselves will materially aid in preventing any dislodgement of the edging strip.

But, if necessary, the side lips of the rubber channeled strip may be amalgamated to the surfaces of the cover by means of any suitable cement, and therefore the invention is not limited in this respect.

While it is preferred to use the channeled rubber strip, nevertheless it is within the scope of this invention to employ a channeled strip of felt or other suitable material, and to secure the latter under tension by means of the clips 6 in the manner hereinbefore de scribed, and in this instance the side lips of the strip would preferably be cemented to the surface of the cover.

Vfhat is claimed is 1. A book cover having a channeled strip positioned around the edges of the covers and secured under tension by means of metal clips which embrace the end portions of said strip and are fastened to the cover.

2. A book cover whose edges are protected by a channeled rubber strip which is placed under tension, the end portions of said strip terminating near the upper corners of the cover and clamped thereto by means of clips that embrace said cover and portions and are riveted to the cover.

3. A construction as in claim 1 in which the outer extremities of the clips are formed into hinge eyes.

4. A construction as in claim 1 in which the end portions of the strip are adjacent the upper corners of the cover whereby, when the clips are clamped to said portions, accidental dislodgment of the strip is prevented.

In testimony whereof I affix my signature hereto.

FRANK S. SCHADE.
